Write a New Prescription on the Desktop

Start a new prescription.

All new prescriptions start from the Medications section of the Patient Dashboard.


To search for the medication, type in the Write Rx box above the medication list. You can also select Fav Drugs to choose a drug from your list of favorites.


If you are unable to locate your medication, especially if it's a new drug, please note that we receive our FDB (Formulary or Medication Database) file on a weekly basis. Currently, we perform manual updates every Thursday morning to ensure the medication is promptly integrated into our system. Users who can wait an additional day to prescribe it will find it readily available. Alternatively, users have the option to add it as a free-text entry in our system. We are working on automating this process in the near future.

Click on the appropriate medication to begin the prescription. It automatically prompts you to add additional information. Choose a Recommended Sig or an existing Custom Sig by clicking on the button to the left of the sig. You'll have the ability to adjust the details.


Formulary Key

Prescribing medications is based on the patient's insurance, and the formulary key explains If a drug is "non-formulary," not included on the insurance company's "formulary" or list of covered medications, etc.


1-means the "least preferred," and 97- means preferred drug." A preferred med is a brand-name drug that may not be available in generic form but chooses its cost-effectiveness compared to alternatives based on the patient's insurance.


Drug-to-drug/allergy interactions

It's important to point out medications and drug-to-drug interaction. 

When prescribing a medication, you may run into a drug-to-drug interaction. In that case, the  Interaction tab will be blinking. 


Selecting the Interactions tab will provide you with the all interaction details and you can select the hyperlink (SELECTED ANTIDIABETIC AGENTS/SELECTED QUINOLONES) and make changes to the medication.


Add prescription details 

Click Calculator to open the pediatric dosage calculator to view the minimum and maximum daily dosage based on the patient's height and weight. It is available for patients under 18 years old.


If no Sigs exist or you need to start from scratch, choose to Create New Sig or the Sig Builder. The Sig Builder is a simplified version of the medication details editor, which allows you to select from listed options and avoid manually keying in details.


If the medication interacts with a patient's allergy documented in RXNT, you may be prompt with an interaction warning. You can accept the interaction or choose to find an alternative for the patient. 


Enter the dosage, quantity, and units for the medication.

 Units options are determined by NCPDP 2017071 prescription standards as required by 42 CFR 170. Prescription units allowable in NCPDP 2017071 are based on a list compiled by the National Cancer Institute.


Complete any additional medication details, click Add Drug to prescribe other medications, or Continue to finish the prescription.



Most of the time, a prescription requires height and weight because the patient is under 18. Below are the different scenarios that could come up, which will work the same, regardless of the patient's age, any time height and weight are needed with a prescription.
  • If you are using the EHR, then the height and weight for the prescription will automatically pull from the most recent vitals for the patient (in the vitals & charting section, based on the date of the entry).
  • If you use ERX only, the height and weight will populate based on previous prescriptions. For new patients, or patients that haven't previously been prescribed medications requiring height and weight, these will be blank, and the provider will need to enter them. For patients previously prescribed medications requiring height and weight, these fields populate with the last entered height and weight, and the provider can edit the information as needed.


Select a pharmacy

Choose the pharmacy by clicking on the name of the pharmacy from the list. The patient favorite Pharmacies will automatically show, but you can also view Prescriber Favorite Pharmacies or search for a new pharmacy using the search options. (Note: If you are prescribing a controlled substance, ensure that the selected pharmacy has EPCS listed in the Type column. This means that the pharmacy is certified to accept controlled substance prescriptions electronically.)


Save or send the prescription 

On the prescription preview screen, you'll be prompted again if there are any interactions for the medication. You'll also have the option to edit any prescription information before sending it. If you're ready to send the prescription, click Send to transmit it to the pharmacy. If any controlled substances are included, you'll be prompted to enter your RXNT account password and your token OTP for two-factor authentication.



If you are setting this prescription up on behalf of a provider, and it either contains any controlled medications or you don't have access to send prescriptions on behalf of the provider, click Save as Pending to save the prescription for provider approval.
